Solution Overview
Problem
Existing charging systems for electric vehicles require multiple systems when multiple vehicles need to be charged, which can be space-consuming and complicate vehicle parking and movement.
Innovation Solution
A system with a charging input coupling, a charging output coupling, and an electric switching device that can selectively direct electric power to either a battery system or an external device, allowing multiple vehicles to be charged from a single source without the need for separate charging systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple charging systems are provided to charge multiple vehicles, then the charging capacity is improved, but the space consumption and difficulty of parking/moving vehicles increases
Solution Approach 1:
The patent applies multi-functionality by enabling a single charging system to serve multiple vehicles through vehicle-to-vehicle power transfer. The first vehicle acts as both a powered vehicle and a mobile charging station, allowing the charging port to function dually for self-charging and external power provision, thereby eliminating the need for multiple fixed charging systems
Solution Approach 2:
The patent uses the first vehicle as an intermediary between the power source and the second vehicle. The first vehicle receives power from an external source and transfers it to the second vehicle through wireless power transfer technology, acting as a mobile power bank that mediates the charging process without requiring direct connection between the power source and each vehicle
2Productivity
If multiple charging systems are provided to charge multiple vehicles, then the charging capacity is improved, but the complexity of parking and moving vehicles increases
Solution Approach 1:
The patent extracts the charging function from fixed infrastructure and relocates it to the vehicle itself. By equipping the first vehicle with charging capabilities, the system removes the need for external charging stations, thereby simplifying the parking and moving environment while maintaining multi-vehicle charging capacity
Solution Approach 2:
The first vehicle provides self-service charging capabilities by acting as a mobile charging station for the second vehicle. This self-service approach eliminates the need for complex external charging infrastructure and simplifies the overall system while enabling multiple vehicles to be charged
